ANT-LIKE SPIDERS FROM MALAYA. 



315 



Pedicel shortish. 



Opisthosoma, as whole spider, rather squat. 



Note. — The description is based on a single from Biserat, 

 length 6*2 mm. Its general shape reminds one of M. maxil- 

 losa 2 •

This spider was found in company with ants nos. 2 and 17. 

 It is very probably a c? of M. maxillosa, which it strongly 

 resembles in general shape and colouring, all its features being 

 those of maxillosa exaggerated even to the falces. The only 

 distinct difference is in the spine pairs. It is the only 3 in the . 

 collection the least like the 2 maxillosa, which is so common, 

 and I should not have hesitated to claim it as the 3 did it not 

 differ so strongly as regards teeth and tibial spines from ThorelFs 



3 M. (Toxeus) maxillosa. It was found in company with 



3 Epidius longipalpis described above.

Prosoma. — Length a little > opisthosoma — p 4 +t 4 . Caput > • 

 thorax. Front wall slightly projecting in centre and stepped 

 back to eyes 2. Side walls straight, very slightly approaching 

 backward. Bac^k wall nearly straight. Groove not marked from 

 above, but walls of thorax going on nearly straight with slight 

 convex and then concave slope to rear, which is cut nearly square 

 and about \ greatest width and strongly rimmed. 



On side view caput flat but convex near eye 4, back slope 

 steep, groove about § caput, the broad thorax rises convexly to 5 

 and then falls gradually convexly and concavely to rim, which is 

 shallow. 



Eyes. — 1st row straight by summits, 1 . 1 in contact ; 2 subcon- 

 tract with 1 and a little stepped back, — j 1 . Eye square broader 

 than long, parallel. 3 slightly nearer 2 than 4. 4 > 2. 4 . 4 =z 

 4-rim. 



Falces. — Length — cephalothorax, breadth =r J length . From 

 above inner edge straight, outer convex, being widest at f , end 

 cut square. From side slightly concave above, below a double 

 flat step to then straight to end. Lighter colour and granu- 

 lated. Unguis > § paturon, bisinuate, with basal curve nearly 

 flat, simple. Teeth, upper 6 or 7, of which 1st is very strong at 

 root of unguis and pointing forward, 2 or 3 close to it, and 

 remaining teeth at other end of groove and wide. Lower 7 to 9, 

 subequally spaced and decreasing from base to apex of unguis. 

 Groove well marked. 



Maxillw. — As turriformis, but outer corner sharp. Length =c x .
